摘要:
A method of detecting high-grade dysplasia, pancreatobiliary cancer, or metastatic cancer to the pancreatobiliary tract or inferring an increased risk thereof, comprising obtaining a sample of pancreatobiliary cells from a patient with a set of detectably labeled probes comprising a locus-specific probe for MCL1 (myeloid cell leukemia sequence 1), a locus-specific probe for EGFR (epidermal growth factor receptor), a locus-specific probe for MYC, and a locus-specific probe for P16 under hybridization conditions and determining the presence of chromosomal abnormalities; a set of probes comprising a locus-specific probe for MCL1, a locus-specific probe for EGFR, a locus-specific probe for MYC, and a locus-specific probe for P16; and a kit comprising the set of probes and instructions for detecting high-grade dysplasia, pancreatobiliary cancer, or metastatic cancer to the pancreatobiliary tract, or inferring an increased risk thereof, in a patient.
摘要:
Probe sets and methods of using probes and probe sets for selectively detecting high grade dysplasia and esophageal adenocarcinoma or low grade dysplasia from biologic samples are described. Methods of the invention include contacting a biological sample obtained from a subject with a set of chromosomal probes to selectively detect an esophageal carcinoma or precursor lesion in the sample, if any, under conditions for specifically hybridizing the probes to their nucleic targets present in the sample. The presence or absence of high grade dysplasia and esophageal adenocarcinoma or low grade dysplasia is thereafter specifically determined from the hybridization pattern detected for the set of chromosomal probes to the biological sample.
